In an interview with Business Insider, President Bill Clinton's
former campaign manager said that while he disagreed with former
Republican presidential nominees like Sen. John McCain of Arizona
and former Gov. Mitt Romney of Massachusetts on policy, they were
far better versed in the details of governing than the current
GOP nominee.

"We'd say in Louisiana, he don't know jack s---," Carville said
of Trump.

"There's certain elementary knowledge [you need] to be in
anything in politics, much less the president of the United
States," he added.

"For one minute, digest a 35% tariff — assuming that you'd ever
put it on — but imagine you'd even threaten that," Carville said.
"What would that do? How would the markets react to the fact that
we're entering a trade war?"

Carville acknowledged that he found Trump "kind of funny,"
brushing off observers who point out that Trump draws larger
crowds to his campaign events than Clinton draws to hers.

"Somebody said, 'Well, he gets bigger crowds than Hillary.' And
my answer is, 'Yeah, more people line up to see a trainwreck than
a traffic light,'" Carville said. "So what the hell does that
mean?"

The Clinton campaign and its allies have frequently attempted to
cast doubt on the real-estate magnate's ability to effectively
manage US relationships abroad. Earlier this month the campaign
rolled out a letter cosigned by numerous Republican
foreign-policy experts
denouncing Trump's policies and positive statements about
Russia.

Trump has responded in kind, accusing Clinton and the Obama
administration of neglecting to quash the unrest in Syria that
led to the rise of ISIS.

"Hillary Clinton's reckless policies unleashed ISIS onto the
world," Trump said in a Wednesday speech in Florida. "She will
never have the judgment or the stamina to fix the problems she
created."
